Description

Technical Field

[0001] This utility model relates to the technical field of automotive electrostatic testing equipment, and more specifically, to an automotive electrostatic testing device. Background Technology

[0002] In the production and testing of automotive electronic equipment, electrostatic discharge (ESD) testing is a key step in ensuring the equipment's anti-interference performance and stability. As the level of automotive intelligence increases, the requirements for ESD protection of various electronic modules are becoming increasingly stringent.

[0003] Utility model patent application number: CN202021057391.8 discloses an electrostatic testing device for automobile inspection, belonging to the field of automobile inspection technology. It includes a base plate, with support plates fixedly connected to both sides of the upper surface of the base plate, and fixed plates fixedly connected to the opposite surfaces of the two support plates. A movable block is slidably connected inside the fixed plate, and a spring a is fixedly connected between the outer side wall of the movable block and the inner side wall of the fixed plate. A fixed sleeve a is embedded and fixedly connected inside the movable block, and a movable rod is sleeved inside the fixed sleeve a.

[0004] While the aforementioned patent can achieve the clamping of electronic devices and the raising and lowering of test probes, it has shortcomings in practical applications. It requires manual operation by pulling the pull ring to clamp the device and pushing the push block to control the raising and lowering of the probe. The whole process requires frequent manual operation, which is not only cumbersome and inefficient, but also the clamping and testing actions are independent of each other. The staff must first complete the device fixation and then operate the probe raising and lowering test separately. The operation process is fragmented, which makes it difficult to improve the efficiency of electrostatic testing of electronic devices and meet the rapid testing needs of large-scale production.

[0005] Therefore, we have made improvements to this and proposed an automotive electrostatic testing device. Utility Model Content

This invention utilizes a synchronous transmission structure consisting of a cylinder drive, gear shaft, belt, and lead screw to transform a single power source into a coordinated action of equipment clamping and test probe lifting. After the cylinder is activated, the drive plate moves the U-shaped sliding plate to clamp the equipment. Simultaneously, the gear shaft rotates and transmits power via the belt, causing the lead screw to drive the test probe to descend precisely. This avoids the cumbersome steps of manually operating clamping and testing separately, improving testing efficiency and addressing the problems of independent operation and low efficiency in existing devices.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] An automotive electrostatic discharge (ESD) testing device includes a base housing. A gear shaft is rotatably fitted onto the inner wall of the base housing. Two U-shaped sliding plates are arranged opposite each other inside the base housing. A toothed plate is fixedly connected to one side of each of the two U-shaped sliding plates. A U-shaped frame is slidably and elastically fitted to one side of each of the two U-shaped sliding plates. Multiple snap-fit ​​components are provided on one side of each of the two U-shaped frames.

[0009] Furthermore, the U-shaped frame is disposed on the upper side of the toothed plate, the toothed plate is disposed inside the bottom shell, the drive plate is slidably fitted on the lower side of the bottom shell, and the upper side of the drive plate is fixedly connected to the lower side of one of the two U-shaped slide plates.

[0010] Furthermore, the snap-fit ​​assembly includes L-shaped connecting rods rotatably engaged at both ends of the U-shaped frame, with rubber wheels rotatably engaged at both ends of the L-shaped connecting rods, and a spring fixedly connected to one side of the L-shaped connecting rods, with one end of the spring fixedly connected to one side of the U-shaped frame.

[0013] Furthermore, a strip groove is provided on one side of the inner wall of the bottom shell for the belt to pass through.

[0014] Furthermore, a plurality of dovetail slide rails are fixedly connected to the lower side of the inner wall of the bottom shell, the lower side of the U-shaped slide plate is slidably engaged on the dovetail slide rails, and a placement plate is installed on the upper side of the bottom shell.

[0015] Furthermore, the electrostatic tester is mounted on the upper side of the support plate, and the test probe is slidably fitted on the lower side of the support plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model transforms a single power source into a coordinated action of equipment clamping and test probe lifting by setting up a synchronous transmission structure of cylinder drive combined with gear shaft, belt and lead screw. After the cylinder is started, the drive plate moves the U-shaped slide to achieve equipment clamping. At the same time, the gear shaft rotates and transmits power through the belt, so that the lead screw drives the test probe to descend accurately. This avoids the cumbersome steps of manual operation of clamping and testing, improves the testing efficiency, and improves the problem of independent action and low efficiency of existing devices.

[0018] 2. This utility model, by setting a snap-fit ​​assembly structure with a spring and a rubber wheel, allows the spring to be compressed when the U-shaped frame approaches the equipment, causing the rubber wheel to adaptively conform to the surface of the equipment, thus achieving flexible clamping. This structure is compatible with electronic devices of different sizes and shapes, eliminating the need for frequent manual adjustments to the clamping angle and force, and improving the problem that traditional devices are difficult to adapt to various devices. At the same time, the buffering effect of the rubber wheel and the spring prevents damage to the surface of the equipment. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Please refer to Figure 1-6 An electrostatic discharge (ESD) testing device for automobiles includes a base shell 1. A gear shaft 2 is rotatably fitted to the inner wall of the base shell 1. Two U-shaped sliding plates 3 are arranged opposite each other inside the base shell 1. A toothed plate 4 is fixedly connected to one side of each U-shaped sliding plate 3. A U-shaped frame 5 is slidably and elastically fitted to one side of each U-shaped sliding plate 3. Multiple snap-fit ​​components 6 are provided on one side of each U-shaped frame 5. A cylinder 7 is mounted on the lower side of the base shell 1. A drive plate 8 is fixedly connected to the output end of the cylinder 7. A lifting shell 9 is fixedly connected to one side of the base shell 1. An ESD tester 10 is mounted on one side of the lifting shell 9. A test probe 11 is provided at one end of the ESD tester 10. A synchronization mechanism 12 is provided inside the lifting shell 9. The U-shaped frame 5 is located on the upper side of the toothed plate 4, which is located inside the base shell 1. The drive plate 8 is slidably fitted on the lower side of the base shell 1, and the upper side of the drive plate 8 is fixedly connected to the lower side of one of the two U-shaped sliding plates 3. Multiple dovetail slide rails 13 are fixedly connected to the lower side of the inner wall of the bottom shell 1. The lower side of the U-shaped slide plate 3 slides and engages with the dovetail slide rails 13. A placement plate 14 is installed on the upper side of the bottom shell 1. Automatic clamping and testing are achieved through mechanical linkage, improving efficiency. The dovetail slide rails 13 and lead screw 122 ensure stable and precise movement. The elastic locking component 6 is compatible with various equipment to avoid damage. The overall structure is compact and practical, reducing the risk of manual operation.

[0029] Specifically, starting cylinder 7, drive plate 8 drives U-shaped slide plate 3 to move along dovetail slide rail 13, and gear shaft 2 is rotated by meshing with gear plate 4. Gear shaft 2 drives drive wheel 126, and screw 122 is rotated by belt drive, realizing the lifting and lowering of test probe 11. At the same time, U-shaped slide plate 3 drives U-shaped frame 5 to approach electronic equipment. Rubber wheel 62 of clamping component 6 elastically clamps the equipment under the action of spring 63, and finally completes electrostatic test.

[0030] In this embodiment, the clamping assembly 6 includes L-shaped connecting rods 61 rotatably engaged at both ends of the U-shaped frame 5. Rubber wheels 62 are rotatably engaged at both ends of the L-shaped connecting rods 61. A spring 63 is fixedly connected to one side of the L-shaped connecting rods 61, and one end of the spring 63 is fixedly connected to one side of the U-shaped frame 5. The combination of the rubber wheels 62 and the spring 63 achieves flexible clamping, avoiding scratches and pressure damage to the surface of electronic devices caused by rigid contact, thus protecting the device's safety. Furthermore, this structure can adapt to electronic devices of different sizes and shapes, eliminating the need for manual adjustment of the clamping angle and force, expanding the applicability of the device, improving testing efficiency, and providing stable clamping to prevent the device from shaking during testing and affecting the test results.

[0031] Specifically, when the U-shaped frame 5 moves toward the electronic device under the drive of the U-shaped slide plate 3, the rubber wheels 62 at both ends of the L-shaped connecting rod 61 first contact the surface of the device. As the U-shaped frame 5 continues to approach, the spring 63 is compressed and deformed, causing the L-shaped connecting rod 61 to rotate around its pivot point with the U-shaped frame 5. The rubber wheels 62 adjust their angle accordingly, closely fitting the surface of the device, and under the elastic force of the spring 63, apply a stable clamping force to the device. Throughout the process, the rubber wheels 62 can roll along the surface of the device, adapting to different shapes of the device contours.

[0032] In this embodiment, the synchronization mechanism 12 includes a rectangular groove 121 formed on one side of the lifting housing 9. A lead screw 122 is rotatably fitted to the lower side of the inner wall of the rectangular groove 121. A driven wheel 123 is fixedly connected to the lower end of the lead screw 122. A lifting seat 124 is threaded onto the lead screw 122. A support plate 125 is fixedly connected to one side of the lifting seat 124. A drive wheel 126 is fixedly connected to the lower end of the gear shaft 2. The upper end of the lead screw 122 is rotatably fitted to the upper side of the inner wall of the lifting housing 9. The lifting seat 124 is slidably fitted to the inner wall of the lifting housing 9. The drive wheel 126 and the driven wheel 123 are connected by a belt tensioning connection. A strip groove 15 for the belt to pass through is formed on one side of the inner wall of the bottom housing 1. An electrostatic tester 10 is mounted on the upper side of the support plate 125, and a test probe 11 is slidably fitted on the lower side of the support plate 125. The synchronization mechanism 12, through transmission components such as gear shaft 2, belt, and lead screw 122, transforms a single power source (cylinder 7) into the coordinated action of multiple components, achieving precise synchronization of the clamping of electronic equipment and the lifting of the test probe 11. This eliminates the need for separate manual operation, greatly improving testing efficiency. The lead screw 122 transmission has high precision, accurately controlling the lifting position of the test probe 11 and ensuring precise docking with the test point of the electronic equipment, thus improving the accuracy and stability of the test. The entire synchronous transmission structure is compact and operates stably, reducing human error and making the testing process more automated and intelligent.

[0033] Specifically, when the cylinder 7 drives the drive plate 8 to move the U-shaped slide plate 3, the toothed plate 4 on the U-shaped slide plate 3 meshes with the gear shaft 2, causing the gear shaft 2 to rotate. The drive wheel 126 at the lower end of the gear shaft 2 rotates accordingly, transmitting power to the driven wheel 123 via a belt. The driven wheel 123 drives the lead screw 122 to rotate. Since the lifting seat 124 and the lead screw 122 are connected by a thread and the lifting housing 9 is restricted to linear motion, the rotational motion of the lead screw 122 is converted into the vertical linear motion of the lifting seat 124, thereby driving the support plate 125 and the electrostatic tester 10 and test probe 11 mounted on it to move up and down synchronously. During this process, the rotation of the gear shaft 2 simultaneously controls the movement of the U-shaped slide plate 3 (to clamp the electronic device) and the lifting of the test probe 11, ensuring that when the electronic device is clamped in place, the test probe 11 is also moved to the appropriate test position.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
